Abstract/Contents:"Common bermudagrass (Cynodon dactylon) L. Pers.) is a widely grown, warm-season turfgrass. The species is characterized for creating a dense, deep-rooted canopy with high levels of drought and traffic tolerance. However, most cultivars present poor shade tolerance which limits the potential expansion of this grass into partially shaded areas. The identification of new sources of genetic resistance to shade and drought among African bermudagrass materials will expand the germplasm pool available to breeders for development of improved bermudagrass cultivars. In this study, 24 common bermudagrass accessions collected from South Africa were evaluated for their ability to persist under 63% shade and for their performance under drought stress. A turfgrass performance index (TPI) was used to identify top performance lines across evaluated traits. Preliminary analysis showed that under no stress, seven accessions had comparable performance to 'Celebration' and 'Tiftuf' across traits and locations. Under drought stress, only one accession was identified with resistance. Under shade, Stil03, Q47620, 'Tifgrand', WIN10F, 'Celebration', and 'Tiftuf' exhibited the highest TPI. Superior accessions identified in this study can be used in future breeding efforts to combine shade and drought tolerance in bermudagrass."
